This is built as part of geometry collection DDC contents.
Reworked scene proxy to use this data. Some big changes there:
* Tidied up hit proxy code so that all hit proxy clients use the same path.
* Removing of internal faces are now handled without an additional index buffer by always storing internal faces at the end of a section and providing different section descriptions for including internal faces.
* Dynamic geometry hiding in editor is now done by zeroing transforms instead of rebuilding the index buffer.

Original CL Desc
-----------------------------------------------------------------
Updated the static mesh property("RootProxy") in UGeometryCollection to be a FGeometryCollectionProxyMeshData which currently contains an array of static meshes.
Deprecated the old RootProxy property in UGeometryCollection. Old data will still work.

- add explicit tracking of internal surfaces in fracture geometry, and remove concept of 'internal-only' materials in odd-numbered slots.
- add tooling to set internal materials, and to set default internal materials to be assigned on fracture
- add option to preserve internal face data via odd material numbers in ToMesh tool + option to re-import these ToMesh outputs w/ internal material IDs set

- Better support for bounds computation using transform bounding box attribute ( this code path can now use ISPC )
- make sure that using ISMPool is equivalent to having visible geometry in the TickComponent method

- avoid calling it over and over when components using the same asset are registered
- make creation of physics state faster
- make duplication of components faster

- Improved InitializeMaterials to be able to handle material list only made of external materials
- Added CollectionInstancedMeshFacade and update code using the attribute directly to use the facade instead
- Added new input / output to Geometry Collection Terminal node ( InstancedMeshes )
- Simplified FindOrAddAutoInstanceMesh methods

[CL 23370012 by cedric caillaud in ue5-main branch]
- Added a Proximity tool to Fracture Mode to visualize and change generation settings for GeometryCollection bone proximity.
- Added more user controls for how proximity is generated, including a "Convex Hull distance" method for deciding contact, which should help include connections that were missed by the default proximity detection method.
- Made proximity settings live on the GeometryCollection as (non-cooked) attributes, so proximity re-generates with the desired method after further fracturing/clustering.
- Added an option to automatically convert the proximity graph to a pre-computed connection graph used by simulation.
- Reduce redundant proximity calculations: Be more consistent in relying on FGeometryCollectionEdit to update proximity as needed, and call 'RequireProximity' instead of 'UpdateProximity' in cases where we expect a valid proximity may already be present.

Limitations : Currently this requires the GC to be reset to recompute the list of instanciable meshes and their corresponding indices
Mitigation : this can be turned off using the following cvar : p.Chaos.GC.UseISMPool
